GENEVA (Reuters) - Up to 1 million people could be driven from their homes in northern Iraq soon as fighting intensifies in a government offensive to retake Mosul from Islamic State, the International Committee of the Red Cross (ICRC) said on Friday.

U.S.-backed Iraqi forces have stepped up their campaign against Islamic State militants in an expected push on Mosul, Iraq's second largest city and the militants' biggest bastion, later this year.
